I wondered whether exist kind of software for complex PCB polygon impedance calculating? Or just Rdc value between some pair of pads, that included to the copper pour. Anybody saw such tool ever? I guess it's would be useful thing for high current SMPS.

Oh thanks jcx,
actually I lost any hope to find something, and start to programming my own simple solution with gerber or even bitmap PCB polygon input. At moment I evaluate the QF5.5, during half of hour manual reading, I find this stuff pretty complex yet. How you made import PCB polygon to QF?

Maybe its not exactly what you need (or a bit over the top) for your purposes .
But personaly i like the ansoft software for magnetics .
Just look with google for ansoft hfss and in case of inductors & transformers pexpert .

I hope this is usefull for you .
